American Hoist and Derrick in Portland (4 acres) manufactured steel, galvanized steel and industrial hardware. The facility generated spent pickle liquor, solvents, coolants nitric and sulfuric acid and metals as wastes. These waste were stored in a 50,000 gallon concrete tank and two 10,000 gallon underground storage tanks. A buried railroad car was used to store fuel oil on-site. Human exposures to contaminants have been controlled at the facility as a result of previous investigation and cleanup activities. Documentation is currently being prepared that will conclude that contaminants released to the groundwater are being controlled.
